This morning I tried getting a short video to work as part of a Keynote slide for the Christmas Show. Only it didn’t work – only the sound played. A quick google turned up a few options:
- Turn off display mirroring. This did seem to work, but it’s a pain.
- Tick the box ‘Allow Exposé, Dashboard and others to use screen’ in Keynote>Preferences>Slideshow.
The second option definitely worked better! For those interested, in the Keynote preference file, it’s called ‘PresentationModePlayWellWithOthers’.
